A vibrant, messy mash is a great way to sneak green veg onto plates where it otherwise might not be welcome. It’s chunky and unpretentious and delicious and we like it very much. Along with some grown up balsamic onion (which actually goes down a treat with little ones), your steak is in very good company.

Produced in a facility that processes eggs, milk, fish, peanuts, sesame, shellfish, soy, tree nuts, and wheat.

Cooking Steps

Prepare the broccoli
1

To prepare the ingredients, cut the stalk off the broccoli and cut into 2 cm pieces. Cut the head of the broccoli into small florets and set aside. Cut the sweet potato into 2 cm chunks (unpeeled) and slice the red onion.

Boil the veggies
2

Place the sweet potato and broccoli stalks in a large saucepan and cover with water. Bring to the boil. Cook for 10 minutes, or until the sweet potato is tender. Add the broccoli florets and cook for a further 2 minutes, or until tender. Drain and return the sweet potato and broccoli to the same pan. Add half the butter, a splash of milk and a generous pinch of salt and pepper. Mash with a potato masher until it reaches the desired consistency (we like ours chunky and a little lumpy).

Rest the steaks
3

Meanwhile, season the premium beef rump steaks with salt and pepper. Get your large frying pan nice and hot. Add the steaks and cook for 4 minutes on each side on a high heat for medium rare, or until cooked to your liking. Remove from the pan and set aside on a plate, covered with foil to keep warm. Rest for 5 minutes. Slice into 4-5 pieces. Tip: always rest your steak, it’s essential in ensuring your meat is juicy and tender.

Caramelise the onion
4

Melt the remaining butter in the same pan with a splash of olive oil (so the butter doesn’t burn) over a medium-high heat. Add the red onion and cook, stirring, for 3 minutes, or until the onion has softened. Add the balsamic vinegar and brown sugar and cook for a further 3 minutes, or until the onion becomes sticky.

5

To serve, divide the chunky vegetable mash and the beef steaks between plates. Top the steaks with the sticky caramelised onions and enjoy.
